Improvement in freight-car doors



UNITED STATES PATENT OEEIcEo GEORGE w. PEELON, OE OEIOAGO, ILLINOIS.

IMPROVEMENT IN FREIGHT-CARV DOORVS.

Specification forming part of Letters Patent N0. 158,732, dated January 12, 1875; application led December 15, 1874.

To all whom it mcy concern:

Be it known that I, GEORGE W. PEELON, of Chicago, in the county of Cook and State of Illinois, have invented a Freight-Gar Door, of which the following is a description, referenre being had to the accompanying drawing', which forms a part of this speciiicat-ion.

My invention relates to that class of freightcars which areused more especially for the transportation ot' grain in bulk; and my invention consists in the special mechanism hereinafter fully described, by means of which I am enabled to slide the car-door up and swing it to the top of the car.

In the annexed drawing, Figure 1 represents a longitudinal section of a freight-car, showing the inside thereof. Fig. 2 represents a transverse section,'showing one door swung to the top ofthe car, and the other door down in position. Fig. 3 represents a transverse section Ot' the grooved iron A; and Fig. 4 represents a side View ot' the pivoted catch and spring, which hold the door in its elevated position.

A is a grooved iron piece, attached to the side post of the doorway ot' a freight-car. B is the door, having metallic end pieces C, which slide in the grooves in the metallic pieces A. D are pins or trunnions on the upper corners of the doors. E are pivoted dogs placed in the top of the pieces A, thesepieces being slotted to receive these pivoted dogs E, which are pivoted at F. G are springs,placed behind the lower ends of these pivoted dogs to keep them iii the position shown by dotted lines in Fig. l.

When it is desired to remove the grain from the car, the door B is slid up to the top thereof. The pins or trunnions D slide into the notches in the pivoted dogs, and the door hangs suspended thereon.

One side of the grooved metallic pieces A is cut away at H, so that when the door hangs suspended on the pivoted dogs, as described, it will swing from the groove in the metallic pieces A into the car in the position shown in Fig. 2, where it is held by a hook, I. J are pins in the top of the grooved metallic pieces A, forming a stop for the pivoted dogs to strike against, and also a stop for the pins or trunnions D to strike against as the door is raised.

It will be observed that the attachment of my door to a freight-car to be used when the car is used for the transportation of grain, does not interfere with the use ot' the ordinary freight-car door; neither does it interfere wit-h the use ot' the car for other purposes than the transportation of grain when the door is swung to the top of the car, as shown in Fig. 2.

My door has the advantages of always being attached to the car in a convenient position, where it can be readily brought into use, and at the same time not be liable to be inisplaced or destroyed, as is the case with the grain-car doors that are removed from the cars when the car is used for other purposes.

I claiml. The combination, in a freight-car, ot the grooved metallic pieces A and pivoted dogs E, as and for the purpose set forth.

2. The door B, provided with the metallic end pieces O, and pins or trunnions D, as and for the purpose set forth. 4

The combination, in a freight-car, of the sliding door B, provided with end pieces and trunnions, with the grooved metallic pieces A, substantially as and for the purposes specied.
